Synthesis and evaluation of actinide imprinted resins
… resins have previously shown good results with application to actinide separations. Large portions of recent research have been dedicated to the synthesis and evaluation of resins with phenolic-type functional groups. Other recent chemical research with lighter metals has developed a …

Desenvolvimento de Modelos Químico - Quânticos para o Estudo de Complexos com Íons Lantanídeos e Actinídeos
… em 1994, o modelo SMLC, Sparkle Model for Lanthanide Complexes, tem sido utilizado apenas para o cálculo das geometrias do estado fundamental de complexos de Eu(III). Neste trabalho, aperfeiçoamos em muito este modelo para o íon Eu(III) e iniciamos o procedimento de extensão do mesmo para os …

Aqueous and solid phase interactions of radionuclides with organic complexing agents
Characterising the geochemistry and speciation of major contaminant radionuclides is crucial in order to understand their behaviour and migration in complex environmental systems. Organic complexing agents used in nuclear decontamination have been found to enhance migration of radionuclides at …
